Benefits of technology

[0030] As described above, the present invention can be applied to provide a general-purpose measuring apparatus utilizing a hydrogen flame by simple constitution. In addition, fuel gas and burner air

Problems solved by technology

That is, the conventional measuring apparatus requires a high-pressure gas container for the fuel gas and refined air, and when used as a transportable measuring apparatus, is limited to the one carried in vehicles, and the apparatus should be transferred to a previously specified place where it can be installed and the high-pressure gas containers are prepared as a separate unit, thus limiting measurement conditions to restrict applicability.
In such measuring apparatus, a high-pressure gas container of small volume can also be used for fuel gas and refined air, but when the volume is decreased, the measurable time is reduc

Embodiment Construction

[0042] Hereinafter, the present invention is described in detail by reference to the drawings.

FUNDAMENTAL CONSTITUTION OF THE TRANSPORTABLE MEASURING APPARATUS UTILIZING A HYDROGEN FLAME ACCORDING TO THE INVENTION (FIRST CONSTITUTIONAL EXAMPLE)

[0043]FIG. 1 shows a transportable apparatus for measuring hydrocarbon in automobile exhaust gas, including an FID analyzer, as one embodiment of the apparatus in the present invention. Specifically, the apparatus comprises a sample collection part 1 consisting of a sample collection tube 1a and a primary filter 1b, a transportable measuring apparatus 2 including an FID analyzer, and a sample introduction tube 3 connecting the two. As electric power fed to the transportable measuring apparatus 2, a build-in battery (not shown in the figure) is utilized.

[0044] A sample suctioned from the sample collection part 1 via a sample gas inlet 2a and secondary filter 4a by pump 5a is regulated at constant pressure by a pressure regulator 7a, allowed ...

Abstract

There is provided a general-purpose transportable measuring apparatus utilizing a hydrogen flame capable of measurement for a long time by simple constitution. The transportable measuring apparatus includes: a hydrogen feeding means having Metal Hydride as fuel gas is used, a means of refining air as a burner air is used, and a battery is used as a means of feeding power to the apparatus.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a transportable measuring apparatus utilizing a hydrogen flame, which is useful particularly as a transportable flame ionization measuring apparatus utilizing Metal Hydride as a hydrogen feeding means. [0003] 2. Description of the Related Art [0004] Usually, an air pollution measuring apparatus such as an apparatus for measuring a generating source, an apparatus for measuring environmental air or an apparatus for measuring an automobile exhaust gas constitutes a sampling system provided with a filter, a switching valve, a sample introduction tube, a dehumidifier, a suction pump, a throttling valve and a flow meter between a sample collection position and an analyzer for the purpose of dehumidifying a sample fluid, removing dust or maintaining a constant flow rate as shown in FIG. 11, and the measuring apparatus is fixed and operated near to the sample collection position (see JIS B 7...
